Android Chart - Examples
SciChart Android ships with ~90 Android Chart Examples which you can browse, play with, view the source-code and even export each SciChart Android Chart Example to a stand-alone Android Studio project. All of this is possible with the new and improved SciChart Android Examples Suite, which ships as part of our Android Charts SDK.
This example demonstrates how to create an Android Donut Chart in code.
See Documentation on how to use this type here:
The Android Donut Chart Documentation.
The SciPieChartSurface can be used to render either Pie, Donut or Nested Pie charts in Java.
Donut charts can be animated on show, have legends and support selection of segments, as well as showing and hiding of labels. Data is provided by a number of PieSegments, which are stored in a IPieRenderableSeries.
The full source code for the Android Donut Chart example is included below (Scroll down!).
Did you know you can also view the source code from one of the following sources as well?
- Clone the SciChart.Android.Examples from Github.
- Or, view source and export each example to an Android Studio project from the Java version of the SciChart Android Examples app.
- Also the SciChart Android Trial contains the full source for the examples (link below).
